Materials: All Suncloud lenses are manufactured from optical grade Polycarbonate material with high grade polarizing film incorporated into the lens. The results are glare free viewing through a lightweight lens with high impact resistance for added protection

Base Frame Curve: The base curve is the radius of the sphere measured from the back of the lens. Suncloud features styles with 6 and 8 base frame and lens curvature. Models that include 6 base tend to be more flat relative to your face. While frames and lenses that feature 8 base curvatures, enable the frame and lenses to wrap on the wearer's face

Megol: Many Suncloud frames incorporate hydrophilic Megol features in the nose area and temple tips. These help your glasses hug and stay put on your face in light activity or humid conditions
